CABLE-HANGER.

SPECIFICATION formingpart of Letters Batent No. 685,046, dated October22, 1901- Applieation filed April 1, 1901.

To ctZZ whom it may concern:

Be it known that I, WILLBUR I-LJOHNSTON, a citizen of the United States,residing at Chicago, in the county of 'Cook and State of Illinois, haveinvented a certain new and useful Improvement in Cable-Hangers, (CaseNo. 2,) of which the following is a full, clear, concise, and exactdescription, reference being had to the accompanying drawings, formingapart of this specification.

My invention relates to cable-hangers, and has for its object theprovision of an improved means for attaching the hanger to the cable.

Generally speaking, my invention comprises a band orstrap composed,preferably,of metal and provided at its ends with the members of alocking device, one of the members of the said locking device havingpivotal or rotary connection with the said strap and also adapted forseparable engagement with the remaining lockin g member and havingrotary engagement therewith, the lines or axes about which the saidlocking member rotates with respect tothe strap and the companionlooking member being displaced, so that when the rotating lockin gmember is in one position the ends of the strap may be separated andthelocking members disengaged, or the ends of the strap may be broughtcloser together and the locking members engaged and locked in position.To insure a firm engagement between the locking members, I employ anauxiliary locking device, preferably in the form of cam mechanismadapted for engagement with the rotating locking member and mounted uponthe companion member. This Serial No. 53,851. (No model.)

reference to the accompanying drawings, in whicha Figure l is a sideelevation of a locking device constructed in accordance with my invention, the cable being shown in section. Fig. 2 is a sectional viewthrough the middle portion of the lock. Fig. 3 is a plan view of thestructure shown in Fig. 1. Fig. 4 is a perspective view of thecable-hanger removed from the cable, the supporting-strap being nearlystraightened. Fig. 5 is a perspective view of the cable-supporting loop.

Like parts are indicated by similar characters of reference throughoutthe different figures.

A hanger-strap a is provided with loops 1) b, that engage thebuckle-bars c 0?, provided upon the locking members ef. The lockingmember 6 is'curved transversely to conform to the curvature of thecable. The locking member f is provided with a base g, that extendslongitudinally of the cable It and is curved transversely to conform tothe curvature of the cable. Two cars it are provided at the ends of thebase portion and extend across the cable. These ears are provided withopen sockets 1670, that receive the ears Z Z,

that extend longitudinally of the cable, and

are transversely arranged with respect to the locking member 2. Thesupporting-loop m, composed, preferably, of Wire, is designed to beplaced over the stringer located above the cable, and is'secured to thelockingmember f by having its lower ends passed through holes providedin the ears 2' i. To permit this engagement of the loop with the ears,one of the ears is provided with a slit n, that permits the metal at thehole to be twisted to one side, so that the loop may be readily placedin position by having one endfirst inserted through the hole in theopposite ear, and thereafter the other end of the loop is placed inthehole of the companion ear by'bein'g passed between the separated sidesof the slit, after which the separated portions of the latter ear may bebrought together. The supportingloop m thus has a pivotal connectionwith the locking member f, and the cams o 0, carried upon the ends ofthe supporting-loop, may be swung from side to side. Y

In placing the cable-hanger about the cable the parts may be placed inthe positions indicated in Fig. 4:, Where the pivotal ears are locatedin advance of the buckle-bar c, in which position the ends of the strapare separated. By grasping the nose 6' the locking member 8 may berotated upon the bucklebar 0 to bring this buckle-bar in advance of theears Z Z, thereby drawing the ends of the strap together. Theconstruction of the looking members is such that with the ends of thestrap thus brought closer together the looking members tend to maintainengagement. To more effectively insure the permanency of this engagementbetween the locking members, the locking member e may be provided withcams having curved portions 13 p, with which cams o 0 may haveengagement, the shoulder portions q q of the cams 0 0 having engagementwith the cam portionspp. The extreme ends of the cams 0 0 also engagethe slot '2', provided in the locking member e, to

further insure the locking engagement between the members of thehanger-lock and to hold the loop m in an upright position. \Vhen themembers of the lock are to be separated, the supporting-loop m is swungto one side. \Vhen the loop m is in an upright position, the cams o 0secure the parts e andf together. \Vhen the parts of the cable-hangerare assembled about a cable, as illustrated in Figs. 1, 2, and 3, thecable-hanger will not become separated.

By means of my construction I am enabled to provide a very simple formof cable-hanger, wherein the binding-strap maybe tightly engaged withthe cable and readily clamped in position about the same and firmlysecured in place.

IVhile I have herein shown and particularly described the preferredembodiment of my invention, it is obvious that changes may readily bemade without departing from the spirit thereof, and I do not wish to belimited {130 the precise construction herein set forth;

Having described my invention, I claim as new and desire to secure byLetters Patent-- 1.
